Haddam had a number of early library associations before a permanent library building was dedicated in 1908. The earliest dated back to 1793. It folded in 1808, but was succeeded by the Haddam Library Association in 1818. This library was divided in two in 1820, one half located at the northern end of Middlesex turnpike and the other at the southern end. This library was restarted in 1896 and ten years later Cyprian Strong Brainerd, Jr., a native of Haddam Neck who became a lawyer in New York City, gave funds for a library building. It was built at 920 Saybrook Road on land donated by Judge Ephraim P. Arnold, the grandson of Joseph and Thankful Arnold. The Brainerd Memorial Library was designed by McLean and Wright, a Boston architectural firm. An addition was completed in 1997.
